> InvalidDatatypeValueException is thrown when parsing an XML document that contains a Union data type and the union is contains another simple data type, eg:
> Given this schema:
> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
> <xs:element name="TestDoc">
> <xs:complexType>
> <xs:sequence>
> <xs:element name="SomeElement"/>
> </xs:sequence>
> <xs:attribute name="testAttribute" type="SubString"/>
> </xs:complexType>
> </xs:element>
> <xs:simpleType name="SubPattern">
> <xs:restriction base="xs:string">
> <xs:pattern value=".*\{.*\}.*"/>
> </xs:restriction>
> </xs:simpleType>
> <xs:simpleType name="SubString">
> <xs:union memberTypes="SubPattern xs:string"/>
> </xs:simpleType>
> </xs:schema>
> This XML should be valid:
> <?xml version="1.0" encoding="UTF-8"?>
> <TestDoc xsi:noNamespaceSchemaLocation="TestSchema.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
> testAttribute="true"
> >
> <SomeElement/>
> </TestDoc>
> However an InvalidDatatypeValueException is thrown when validating this document.
> Changing my schema to remove SubPattern from the SubString union, fixes the issue, but it's not the solution I'm looking for.
> I would like xerces-c to validate the document correctly.
